chore: correct changeset guidance in contributing.md and elsewhere

[carderne]

Existing advice says if you have a PR that touches packages AND apps, ONLY do a changeset.

This fixes that to say if your app touches both, you do a changeset AND a .server-changes.

Walkthrough

Updated documentation in .server-changes/README.md, CLAUDE.md, CONTRIBUTING.md, CHANGESETS.md, .claude/rules/server-apps.md, and .claude/REVIEW.md to state that package-only PRs use only a changeset, mixed package-and-server PRs require both a changeset and a .server-changes/ file, and server-component PRs should add a .server-changes/ file. The package-and-server changes tables were also updated to require both artifacts.
